Well stampcollector89, as I'm pretty new at this also I'll put my 2cents worth in.
If you've gotten all or most through the mail the last four years I would pick the country you have the most of and go back 4 or 5 years and start from there. the stamps are listed chronologically in the catalogues. Not every image of every stamp is in there if they were issues in sets they will have one example of that set but they do have a description of what's on the stamp. It sometimes takes me a few passes to find one but I always manage.
Oh yeh I place all my stamps so I can see them ( if I have too many 20 or so at at time. I place the ones that obviously a set together to make the process a little faster.
I managed to identify about 2000 Polish stamp in just short of a week this way ( not forgetting I work full full time.
Hope this helps a little
